Re: [Tutor] Beginner's question

Many, many thanks to all those who replied to my question. I hope the next time I post, it will be with something more advanced. Judging by the volume of replies, is it fair to say that this problem was much too advanced for page 16 of an introductory text? Best wishes, Peter __

Re: [Tutor] Beginner's question

Hi Varun, Thanks for your reply. I agree the problem is logic - but how can one inspect one number using if x%2 == 0 and then compare it to two other numbers which should at the same time be checked for "oddness", just using the basic constructs? Thanks, Peter On 11/22/2012 02:06 PM, Varun
